s/speedups/faster/ - that's nicer and could be sold with easy. Also, why there is no uvloop?

I don't want faster, because it's a name of group of deps, not an action. It's the same as when you call a function with action/verb but you call a var/class as an object.

@asvetlov so what about uvloop?

Just library installation doesn't make sense, uvloop policy should be initialized by asyncio.set_event_loop_policy().

I don't see a place for the call in aiohttp itself.

So I think the idea is to check whether it's present and do it on init.

What do you mean by on init?
I don't see any 100% reliable scenario.
A user always can do weird things, e.g. calling asyncio API before aiohttp import.
If aiohttp will change the default loop policy on import (which is a side effect BTW) previously opened connection will just hang etc.

True. So no uvloop in extras then.
